Frame and plaster anchor



Jan. 28, 1930. A. BAUM FRAME AND PLASTER ANCHOR Filed Sept. 8. 1928 ju/arr ,Zm IM Q Patented Jan. 28, 1930 ISAAC ALBERT BAUM, OF CHICAGO, ILLINOIS FRAME AND PLASTER ANCHOR Application filed September 8, 1928.

IvIy invention relates to building construction, and more particularly to an improvement in metal frame construction, this invention being an improvement over the construction shown in my copending application filed August at, 1928, Serial No. 297,454.

An object of my invention is to provide in association with a channel shaped metal frame element, a plurality of plaster anchors extending at spaced intervals along the sides of the channel flanges. Where lath is not in stalled on the face of the wall and metal buck, the plaster has a very insecure adhesion to the metal of the buck, and as the greatest tendancy toward cracking is at a point adjacent to the door opening, it has been found desirable to provide anchoring devices to insure proper bond.

A further object of my invention is to utilize these plaster anchors as a gauge for insuring a ready alignment of a plaster terminah.

ground or molding which may, if desired, be formed of a single bent strip and welded to. the outside face of the channel flanges.

The various elements illustrated in the drawings accompanying this specification are identical with those shown in my copending application heretofore identified with the exception of the improvement.

The invention will be more readily understood by referring to the accompanying drawings in which:

Fig. 1 is a vertical section through a tile wall showing a construction such as contemplated by my invention and Fig. 2 is a side elevation of the device of my invention.

By referring to the drawing, it will be seen that I have illustrated a tile wall at A, and plaster at B. The device of my invention consists of a continuous metal channel having the web and side flanges 11. A door stop 12 extends longitudinally of the metal frame, and is formed out of the metal thereof. The metal channels are of predetermined uniform width in order that the flanges 11 may have a tight contact with the tile or masonry elements A. By this means, the flange elements are supported by the superposed masonry elements, and the two are Serial No. 304,811.

practically a single unit. Thrusts and blows resulting from slamming of the door against the strip 12 will be transmitted directly to the wall A and the channel will remain solid. On the side of the flanges 11 at a suitable distance from the web as shown in the upper portion of the Fig. 1 and in Fig. 2 I provide a plurality of projections or arcuate ribbons 13. These projections are struck out of the metal in the flanges and function as plaster anchors and gauges to provide an accurate spacing means for the plaster terminals 14. The plaster terminals or molding strip 14 consists of a strip of metal having a flat leg 5 which is welded to the face of the flanges 11 at suitable points. The projecting margin of the strip may be bent in any suitable manner to provide either a plaster anchor, terminal, or molding. I have shown only one form, that being a plaster terminal and anchor the two legs of which are at right angles to each other, the outside margin being rebent at an obtuse angle to provide an anchor.

In the lower portion of Fig. 1 I have shown a slightly different construction in that the flange 11 is imperforate and the ribbons or anchors 13 are struck out of the base 14 of the terminal 14.

A device of the character herein described has numerous advantages. The most important being that the entire structure is capable of simple assembly in the shop and need only to be positioned and the tile wall built up between the flanges. Suitable tile anchors such as I have illustrated at C are further desirable for insuring rigidity.

Even where metal lath is used, the anchors shown herein will be preferred over the usual prongs. The lath may be abutted against the anchors and wired through the openings and the repeated injuries to the hands of the workmen in handling and installing the bucks with prongs is avoided.

A device of the character described is simple and economical to manufacture and may be installed by common labor. A construction such as herein illustrated is especially desirable where plaster is applied directly to the tile, the anchors 13 being very desirable in this connection.

Obviously modifications and variations may be made in the construction herein described, and I do not Wish to be limited except as indicated in the appended claims.

I claim:

1. In framing, the combination of a jamb of channel shape adapted to be mounted at the edge of a masonry wall, a plaster terminal strip Welded to the outer face of said flanges and a plurality of spaced projections formed out of the metal of said flanges, and adapted to serve as anchors and as a gauge for said plaster terminal.

2. In metal frame construction, the combination of a channel shaped metal frame adapted to cooperate with a masonry Wall, and a plurality of bowed plaster anchors formed out of a flange of said channel'and extending longitudinally of said flange, and a combination plaster ground, terminal and molding strip secured to the face of said flange and positioned With an edge in contact with said anchors.

3. In combination, a channel shapedframe element having flanges, an L-shaped plaster terminal strip secured to an outer face of a flange, and struck out loops projecting into the plaster-space adjacent to said terminal strip and serving to anchor the plaster to the channel flange.

In testimony whereof I have afiixed my signature.
